UPDATE INFORMATION
================================================================================
Your site has determined that there is an updated version of Admin Tools
available for download.
New version number: [VERSION]
This email is sent to you by your site to remind you of this fact. The authors
of the software will never contact you about available updates.
================================================================================
WHY AM I RECEIVING THIS EMAIL?
================================================================================
This email has been automatically sent by a CLI script you, or the person who built
or manages your site, has installed and explicitly activated. This script looks
for updated versions of the software and sends an email notification to all
Super Users. You will receive several similar emails from your site, up to 6
times per day, until you either update the software or disable these emails.
To disable these emails, please contact your site administrator.
If you do not understand what this means, please do not contact the authors of
the software. They are NOT sending you this email and they cannot help you.
Instead, please contact the person who built or manages your site.
